REFRIGERATING AND PURIFYING APPARATUS.

SPECIFICATION forming part of Letters Patent N0. 741,855, dated October20, 1903. Application filed October 7, 1901. -Serial1l'o. 7 7,877. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, CARL WILHELM VoLL- MANN, manufacturer, of the cityof Montreal, district of Montreal, and Province of Quebec, Canada, haveinventedcertain new and useful Improvements in Refrigerating andPurifying Apparatus; and I do herebydeclare that the followingisafull,clear, and exact description of the same.

My invention relates particularly to apparatus for use in the coolingand purifying of the holdsof seagoing vessels, although it is applicablefor use in other connections, such as in cold-storage buildings or, infact, wherever it is desired to cool or purify air or other gases.

The invention may be said briefly to consist in providing a series ofpipes and a spraying device Within a closed chamber and forming acircuit to include said series of pipes, spray device, the interior ofsaid closed chamber, a

refrigerating-tank, pipe connections between all of said parts, andmeans for causing a fluid to circulate through said circuit, a supply toand exhaust from said closed chamber of the air or other gas to bepurified and cooled being provided. For full comprehension, however,'ofmy invention reference must be had to the accompanying drawings, formingapart of this specification, in which like symbols indicate the sameparts, and wherein- Figure 1 is a side elevation of my improvedrefrigerating and cooling apparatus with the refrigerating and coolingchamber partly in section. Fig. 2 is a longitudinal vertical sectionalview of the refrigerating and cooling chamber proper; and Fig. 3 .is atransverse vertical sectional view thereof, taken on line 3 3, Fig. 2.

I will first describe a novel cooling-chamber which comprises fluidconducting and spraying devices applicable to my improved apparatus.

The shell I) of my improved chamber is preferably formed with adownwardly-extending receptacle 0, divided therefrom by'downwardly-inclined diaphragms d, and inlet and outlet pipes e and fareprovided to feed the air to be cooled and purified and exhaust samethrough the action of the blower a. The ends of this shell areclosed byplates 9, each having a series of openings in which the respective endsof a bank of pipes h are set, while a pair of hollow heads iand j arebolted or otherwise secured to the outside of said end plates,therebyinclosing the open ends of said pipes and constituting a pair ofauxiliary chambers with the bank of pipes eifecting a communicationbetween them. A spraying device is arranged also within the chamberabove the bank of pipes and consists of a series of pipes 7t, capped atboth ends and having perforations in their under sides, branch pipes Zconnecting said pipes 7c together and a feed-pipe m being connected toabout the middle of said series.

a is the refrigerating-tank, and o the pump for causing a flow throughthe circuit. A pipe 19 connects the lower end of the refrigcrating-tankto the hollow head or auxiliary chamber z', and a curved pipe 0 connectsthe other hollow head j to the feed-pipe m of the spraying device, Whilea pipe 8 connects the receptacle 0 at the bottom of the coolingchamberto the pump and thence to the upper end of the refrigerating-tank.

The circuit through this apparatus just described will be as follows:The chilled fluid,

preferably brine, flows through pipe 19 from the refrigerating-tank toauxiliary chamber.

2', bank of pipes h, hollow head j, pipe 0, to the spraying device,which sprays it through the interior of the chamber, and it collects inthe receptacle 0, the pump 0 causing it to flow back through pipe 8 tothe refrigeratingtank.

This apparatus renders the air both pure and cool and is well suited tosupply the general demand.

What I claim is as follows:

1. A cooling and purifying apparatus comprising a main chamber having anauxiliary chamber at each end of and divided from said main chamber; asupply to and exhaust from said main chamber of the air or other gas tobe treated; a bankof pipes leading from and communicating with one ofsaid auxiliary chambers through said main chamber to and communicatingwith said other auxiliary chamber; a spraying device Within said mainchamber above said bank of pipes; a receptacle at the lower end of saidmain chamber ;a refrigerating-tank located above said main and auxiliarychambers; a pipe leading from said refrigerating-tank to thefirst-mentioned of said auxiliary chambers; a pipe leading from theother of said auxiliary chambers to said spraying device; a pipe leadingfrom said receptacle to said tank; and means for causing the fluid fromsaid tank to flow through said circuit substantially as deing devicewithin said main chamber above said bank of pipes; a receptacle at thelower end of said main chamber; a pipe leading from saidrefrigerating-tank to the first-mentioned of said auxiliary chambers; apipe leading from the other of said auxiliary chambers to said sprayingdevice; a pipe leading from said receptacle to said tank; and means forcausing the fluid from said tank to flow through said circuit,substantially as described and for the purpose set forth.

In testimony whereof I have aifixed my sig nature in presence of twoWitnesses.
